python - 凭据有问题（google smtp）

Question

我是一个非常新的Python 编码器，所以请不要对我太苛刻，谢谢。

我正在尝试使用电子邮件发送器smtplib，但在将用户凭据交给 Google 时遇到了麻烦。

完整代码：

mailcheck = input("This mailer is only for gmail, want to continue? (yes or no)")

# GMAIL SMTP INFORMATION
if mailcheck == "yes" or mailcheck == "Yes" or mailcheck == "y":
    smtp_server = 'smtp.gmail.com'
    port = 587
    set_server = "gmail"
else:
    print("Hey, sorry this program is only for Gmail")

#USER CREDENTIALS + RECEIVER

username = input("Google Email?")
password = input("Password?")
receiver = input("Who to send it to?")
subject = input("Subject of the email?")
econtents = input("What to put in the email?")
amount = input("Amount of emails to send?")

credentials = username + password
global d1
global d2

try:
    server = smtplib.SMTP(smtp_server, port)
    server.ehlo()

    server.starttls()
    server.login(username, password)

    print("Sending" + amount, "to", receiver)

    for i in range(1, int(amount) + 1):
        message = "From" + credentials[0] + '\nSubject' + subject + '\n' + econtents
        time.sleep(random.uniform(d1, d2))
        server.sendmail(credentials[0], receiver, message)
        print("\nEmail Sent!")

    else:
        print("Finished sending emails")

except smtplib.SMTPRecipientsRefused:
        print("Recipient refused. Invalid email address?")

except smtplib.SMTPAuthenticationError:
        print("Unable to authenticate with server. Ensure the details are correct.")

except smtplib.SMTPServerDisconnected:
        print("Server disconnected for an unknown reason.")

except smtplib.SMTPConnectError:
        print("Unable to connect to server.")

错误 ：

Unable to authenticate with server. Ensure the details are correct.

这意味着登录过程出错了。这部分的某个地方应该出错了：

 #USER CREDENTIALS + RECEIVER

username = input("Google Email?")
password = input("Password?")
receiver = input("Who to send it to?")
subject = input("Subject of the email?")
econtents = input("What to put in the email?")
amount = input("Amount of emails to send?")

credentials = username + password
global d1
global d2

try:
    server = smtplib.SMTP(smtp_server, port)
    server.ehlo()

    server.starttls()
    server.login(username, password)

    print("Sending" + amount, "to", receiver)

    for i in range(1, int(amount) + 1):
        message = "From" + credentials[0] + '\nSubject' + subject + '\n' + econtents
        time.sleep(random.uniform(d1, d2))
        server.sendmail(credentials[0], receiver, message)
        print("\nEmail Sent!")

我认为这是因为credentials = username + passwordwhich 不起作用，但我不知道如何解决它。

如果有人知道我必须改变什么来解决这个问题，那就太好了！

不是添加这两个字符串，而是将它们放在一个数组中。在 Python 中，要么

credentials = [username, password]

或者

credentials = list(username, password)

But that doesn't seem to be your issue. Your issue is related to the login() function as you get the SMTPAuthenticationError exception. The smtplib documentation says that after running .starttls(), you should run .ehlo() again. Try to run that before logging in. Additionally, you could try to generate an SSL instance on port 465.

(Ctrl+F for .starttls())
